SINKER-FORMING MOLD.

Application filed March 1, 1924.

To all whom it may concern:

Be it known that I, VILLIAM LINHART, a citizen of the United States, andresiding at New York, in the county of New York and State oi New York,have invented certain new and useful Improvements in Sinker-FormingMolds, of which the following is a specification, such as will enablethose skilled in the art to which it appertains to make and use the.same.

This invention relates to devices for mold ing or casting sinkers suchas used by fishermen, and particularly to a portable device of thisclass, and the object of the invention is to provide a molding toolwhich is so constructed as to permit of the molding or forming ofsinkers o1 different sizes and weights, means being providedv on thetool for indicating the respective sizes of the sinke-rs to be formed;and with this and other objects in view the invention consists in adevice of the class and for the purpose specified which is simple inconstruction,

eliicient in use and which is constructed as hereinafter described andclaimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which Fig. 1 is a side and sectional view of amolding tool made according to my inven tion;

Fig. 2 is a section on the line 22 of Fig. 1; and,

Fig. 3 a perspective detail view of a sinker formed by the mold shown inFigs. 1 and 2.

In carrying my invention into effect, ll provide a portable forming tool5 which, in the construction shown, is fashioned to form a shank portion6 provided at one end with a handle member 7 and at the free end oftially rectangular in cross section the side and end walls of thechamber 10 being parallel in horizontal plane. The taper of the chamber10 which opens outwardly through the top of the body 8 is sul'licient topermit serial-no. 696,124.

of the removal of a molded member formed by the body 8 or the chamber 10thereof.

ndjacent to the lower end 01" the body 8, the side walls tnereof areprovided with op positely disposed apertures 11 which i are tapered toreceive a tapered pin 12, clearly shown in Fig. 2 of the drawing, thepin 12 functioning as a core pin and torn ing an aperture 13 in thecontracted end portion 1 of a sinker 15 as shown in Fig. 3 of thedrawing.

The entire tool, if desired, may be composed of suitable metal, or theshank 6 and hot y 8 may be composed of metal and the handle portion 7 ofinsulating material, if desired, and in the use of the tool in theformation of a sinker oi predetermined size and length, the core pin 12is placed in position and the molten lead or other metal is poured intothe chamber 10 ot the body 8 to iill the chamber to a predetermineddegree which may be represented on one side face of the body 8 bycircular markings 16. In view of the fact that the body 8 is cold themolten metal will immediately be chilled and quickly set.Byremovingthezcore pin12 the casting or molded member may be readilyremoved through :the open .end 10f the chamber 10. It is important thatthe walls of the chamber 10 be smooth and unobstructed to permit of thecasting or molding of perfect sinkers and also to readily permit of theextraction or removal of the sinker when formed.

Instead of proceeding, as above set out, lead or other metal to beemployed in the forming of sinkers may be weighed and dropped into thechamber 10 and the body 8 I placed over a suitable flame or subjected toheat units to melt the lead or other molding metal, and in this way asinker of proper size and weight may be formed.

It will be understood that my improved tool is designed particularly foruse by fishermen or others to permit of the forming of sinkers of anysize or weight to suit predetermined conditions, and by reason of thesimplicity of the tool the same may be sold at a nominal expense withinthe means of the public in general.

lit will be understood that while I have shown and described certaindetails of construction for carrying my invention into effect, I am notnecessarily limited to these details, and various changes therein andmodifications thereof may be made, within the scope of the appendedclaims, without departin from the spirit of my invention or sacrificingits advantages.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. A device of the class described comprising a body portion providedwith a conical chamber, said body portion being provided with atransverse aperture which opens into the contracted end portion of saidchamber.

2. A device of the class described comprising a body portion providedwith a conical chamber, said body portion being provided with atransverse aperture which opens into the contracted end portion of saidchamber, and a core pin adapted to be mounted in said aperture.

3. A device of the class described comprising a body portion providedwith a conical chamber, said body portion being provided with atransverse aperture which opens into the contracted end portion of saidchamber, a core pin adapted to be mounted in said aperture, and saidcore pin and aperture being tapered.

4. A sinker forming tool of the class described comprising ashankprovided at one end with a handle member and the other end of said shankbeing provided with an enlarged body portion provided with a conicalchamber opening through one end of the body portion, and said bodyportion being provided with a transverse aperture adjacent to thecontracted and closed end of said chamber.

5. A sinker forming tool of the class described comprising a shankprovided at one end with a handle member and the other end of said shankbeing provided with an enlarged body portion provided with a conicalchamber opening through one end of the body portion, said body portionbeing provided with a transverse aperture adjacent to the contracted andclosed end of said chamber, and a core pin adapted to be mounted in saidaperture to extend transversely through the contracted end portion ofsaid chamber.

6. A sinker forming tool of the class described comprising a shankprovided at one end with a handle member and the other end of said shankbeing provided with an enlarged body portion provided with a conicalchamber opening through one end of the body portion, said body portionbeing provided with a transverse aperture adjacent to the contracted endof said chamber, a core pin adapted to be mounted in said aperture toextend transversely through the contracted end portion of said chamber,and means on the body portion for designating the several sizes ofsinkers to be formed.

7. A portable molding tool of the class described comprising a mold bodyhaving a substantially conical mold chamber therein, and a core pieceadjacent the contracted end of said conical mold chamber and detachablymounted in said body.

In testimony that I claim the "foregoing as my invention I have signedmy name this 28th day of Feb, 1924.

WVILLIAM LTNHART.
